CARL H. ZWERMANN, OF KALAMAZOO, MICHIGAN.

CLOSET-TANK AND CONNECTIONS.

Application filed August 31, 1911.

To all whom it may concern:

Be it known that I, CARL I-I. ZWERMANN, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Closet-Tanks and Connections, of which the following is a specification.

This invention relates to an improved closet tank and connections.

The objects of this invention are to pro vide an improved construction of closet tank and connections in which leaky joints are overcome and avoided, in an economical and eliicient manner, and in which the valve is so located at so low a level that all sediment is efiectively discharged at each flush.

Objects relating to economies and details of construction will definitely appear from the description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure constituting an effective and preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification. in which:

Figure I is a detail front elevation view of a closet tank and connections embodying the features of my invention, a portion of the tank being broken away to show details of construction. Fig. II is an inverted plan view of a portion of the structure appearing in Fig. I. Fig. III is an enlarged detail sectional plan "iew taken on a line corresponding to line 3-3 of Fig. I. Fig. IV is a detail sectional view taken on a line corresponding to irregular line 4-4 of Fig. III. looking in the direction of the arrows, showing details of construction and arrangement of parts, portions appearing in full lines. Fig. V is a detail view of the tank structure on section similar to Fig. IV, separated and disassembled from the flushing devices.

In the drawing similar numerals of reference refer to similar parts throughout the several views.

Referring to the numbered parts of the drawing, the tank 1 is of sheet metal suitably enameled. and is provided with a cover 2 of any suitable design. The bottom 3 is integral with the sides of the tank, made either by stamping or gas weld. A. sleeve Specification of Letters Patent.

1 is secured in place surrounding the water supply pipe 7, being welded by gas or oxyhydrogen weld joint 5.

The water supply pipe 7 is disposed within the sleeve 4. Any suitable valve fixture 6 is screw threaded at 7 on the upper end and the screw threaded coupling 8 is on the lower end of the pipe 7.

The overflow pipe 9 is secured to the bottom by gas or oxyhydrogen weld to a downwardly-depressed flange 11 disposed somewhat below the plane of the bottom 3 (see Figs. TV and V). The usual flushing coupling 12, with a valve seat 13 at its upper end and flange 13 for engaging the bottom of the tank is provided. This is perforated at 15 below the bottom of the tank and level with the bottom of the cup 16 for the passage of water to the overflow pipe 9 already referred to.

An open bottom cup 16 is conformed to and surrounds the downwardly-projecting flanges 16 which fit against the under side of the tank bottom and are preferably secured by spot weld thereto. The whole is coated with enamel.

A screw threaded nut 17 is provided for the outlet pipe 12 and fits against a gasket 19 which rests against a suitable seat on the under side of the cup member 16. When these parts are placed together, they form practically water tight joints. However, there is no dan er of leakage because the discharge in flushing is within the cup portion 16, and is necessarily drained into the discharge pipe 12, and any pressure on the joints from within the tank is thus avoided. The usual valve ball 14 is provided for the outlet or discharge. and the usual refill pipe 20 is provided for discharging a small quantity of water through the overflow to refill the bowl. The usual lever 21 with suitable connections is provided for controlling the valve 1 1. Any flush device and ball cock may be utilized in this relation.

The tank and the parts welded thereto are coated with enamel to prevent any rusting and leaking.

I have described my improved tank structure and its connections in the most improved form. The cup member might be a separate part although it is of great advantage made integral. It will be clear that the features can be considerably modified in detail without departing from my invention. I show an integral structure accomup within the tank, an open bottomedvcup POItlOIl embracing the sald downwardly projecting flange portion and secured to the bottom by spot weld, an outlet coupling flanged at its upper end with a valve seat in its upper end and with apertures below the bottom of the tank within the cup, and suitable screw connections and gasket for securing the said coupling to the tank, co-

acting substantially as described and for the purpose specified.

2.1n a closet tank and connections, the combination vof a tank of sheet metal. a downwardly struck flange at the bottom of said tank, an overflow pipe secured to the bottom of said flange disposed within the tank,.an 'openbottomed cup embracing the said downwardly-projecting flange portion and suitably welded thereto, and an outlet couplingwith a valve seatin its upper end with threaded nut beneath the .1cup,'-for the purpose specified.

In witness where,of,- I have hereunto 'set my hand and seal in the presence of two witnesses.
